15:14:57 [David_Corvoysier]
Mark: update the url to the meida source proposal already submitted to the W3C
15:15:35 [David_Corvoysier]
Clarke: Source/Track buffers ? any comments
15:15:45 [kaz]
zakim, who is speaking?
15:15:56 [Zakim]
kaz, listening for 10 seconds I could not identify any sounds
15:16:22 [kaz]
15:16:36 [kaz]
15:17:26 [David_Corvoysier]
Clarke: Maybe these terms should be only explaine din the referenced proposals
15:18:28 [David_Corvoysier]
Clarke: Missing Definitions have been posted to local repo: should be upstream soon
15:18:53 [David_Corvoysier]
Clarke: Anything missing in paragraph 4
15:19:14 [David_Corvoysier]
Joe: What was the resolution on the errors ?
15:19:23 [David_Corvoysier]
Clarke: That's still open
15:21:02 [David_Corvoysier]
Clarke: 4.1.2 media tag instead of audio & video ? did that to differentiate from the object tag
15:23:22 [David_Corvoysier]
Clarke: in paragraph 4, one must be very careful with the language used to express the fact that everything should be open, both in terms of solutions and implementations
15:23:36 [David_Corvoysier]
??: open is a loaded word
15:23:39 [kaz]
q+ to suggest we mention ABR stands for Adaptive Bit Rate somewhere
15:23:44 [kaz]
15:24:05 [kaz]
zakim, who is speaking?
15:24:16 [Zakim]
kaz, listening for 10 seconds I heard sound from the following: Clarke (27%), John_Simmons (4%)
15:24:35 [David_Corvoysier]
John: whatever ABR techno is used is not important: enabling a techno is not specifying it
15:25:44 [David_Corvoysier]
Clarke: little uncomfortable with language related to open source browsers
15:26:07 [David_Corvoysier]
John: examples of where this req should apply ?
15:26:51 [David_Corvoysier]
Clarke: I want to avoid to imply that if an ABR solution is not open source, it cannot be made available in an open source browser
15:28:35 [David_Corvoysier]
Mark: some formats will _not_ be supported by all UAs
15:28:56 [David_Corvoysier]
John: To that extent req 4.1.9 cannot fully apply
15:30:18 [David_Corvoysier]
Aaron?: It should be possible to create an ABR system that everybody supports ?
15:30:34 [kaz]
zakim, who is speaking?
15:30:45 [Zakim]
kaz, listening for 10 seconds I heard sound from the following: Clarke (100%)
15:30:59 [kaz]
zakim, who is speaking?
15:31:10 [Zakim]
kaz, listening for 10 seconds I heard sound from the following: Bob_Lund (15%)
15:31:44 [David_Corvoysier]
Aaron: I am not advocating for us choosing a format, but there may be an open source format option, that is a format that could be implemented by every UA
15:31:54 [David_Corvoysier]
John: What is the definition ? RF ?
15:31:59 [kaz]
15:32:37 [David_Corvoysier]
Joe: Is there a W3C definition of what _is_ open source ?
15:33:40 [David_Corvoysier]
Philipp?: By definition, a spec is not source code. The question is whether it can be implemented in an open source environment
15:34:05 [kaz]
-> w3c glossary (just fyi)
15:34:10 [David_Corvoysier]
Philipp?: I don't have the answer: would need to check with open source experts
15:34:17 [kaz]
15:34:27 [David_Corvoysier]
??: Do we need this req altogether ?
15:34:39 [kaz]
15:35:07 [David_Corvoysier]
John: The debate is not open source vesus closed source: it seems more related to being agnostic to ABR systems
15:36:30 [David_Corvoysier]
John: You don't need to specify anything specific to any ABR system, actually: only specify the spec allowing to use them
15:37:22 [David_Corvoysier]
Clarke: Just want to make sure we don't prevent any implementation in open source browser
15:37:52 [David_Corvoysier]
Mark: We are mixing spec and code (and confusing the scribe a lot !!!)
15:38:27 [David_Corvoysier]
Mark: The fact that a specification has to be published for free encourages the implementation of it by open source
15:40:01 [David_Corvoysier]
Mark: The issue in all W3C spec, especially with these two, is that there is nothing implying that the tech below the W3C specs need to be RF also
15:40:45 [David_Corvoysier]
Clarke: I am willing to be convinced that req 4.1.9 is implicit: is that the consensus in the group^
15:42:09 [joesteele]
+1 implicit
15:42:11 [David_Corvoysier]
Aaron: I would say that the W3C spec for ABR or EC must be implementable RF
15:42:47 [glenn]
are you saying that *all* ABR/ECs need to be implementable RF?
15:44:34 [David_Corvoysier]
Juhani?: The API must work with open source browser, but we should not tak any position related to format or the Royalties associated to lower level APIs
15:44:48 [glenn]
i agree that the API itself (that W3C defines) should be implementable RF, but it goes to far to say that the underlying semantics of a specific ABR (that is exposed by that API) must also be implementable RF
15:44:56 [David_Corvoysier]
Clarke: We should to be more explicit in this req
15:44:58 [glenn]
s/to far/too far/
15:45:51 [David_Corvoysier]
Clarke: Still no consensus, will leave it in by default until we work on the wording
15:46:32 [David_Corvoysier]
Joe: Something alogn the lines could be added "To the extent that the W3C already requires specs to be RF"
15:46:49 [Juhani]
15:47:07 [David_Corvoysier]
Clarke: Would suggest wording
15:48:39 [David_Corvoysier]
Bob: Could we be more explicit that audio abd video should support playback of content delivered using ABR
15:49:27 [David_Corvoysier]
Clarke: Will take Bob's suggested wording offline
15:50:52 [David_Corvoysier]
Clarke: About parameters, the clarification that i am trying to make is that we don't limit the number of parameters that can be used, but instead specify a minimum set
15:51:28 [David_Corvoysier]
Clarke: A pretty good starting place here !
15:52:13 [David_Corvoysier]
Clarke: Please take a look at this doc next week, and also on the EC doc (hope the changes will be pushed this time)
